New CollPlant division focuses on 3D bioprinting

Regenerative medicine company CollPlant said Thursday that it has created a new division to focus on collagen-based bioprinting. CollPlant has been utilizing its proprietary plant-based rhCollagen technology for tissue repair. The new division will further develop collagen-based bioink for use in 3D printers creating organs and tissues. The Ness Ziona, Israel–based company says it has 3D

6 ways hydrogels are enabling medtech innovation

Hydrogels are water-based biomaterials developed specifically for human use, according to a Biomaterials journal article. They are a water-swollen polymeric material that doesn’t change its distinct 3D structure. They are formed from super-absorbent, chain-like polymers and are not soluble in water. However, their porous surface allows for nutrients and cell waste to pass through. They have

Aerospace may have something to teach medtech about materials: Here’s how

QuesTek Innovations has used advanced computer modeling to produce innovative materials in the aerospace sector. Now it’s looking to recreate the same magic in the medical device space. Chris Newmarker, Managing Editor Medical device developers typically turn to off-the-shelf materials and then design based on the properties of the materials. But does it have to

Gore’s Viabahn VBX: The very model of a modern major product launch

The Viabahn VBX built by Gore is the first and only balloon expandable stent graft with an iliac indication. It is a balloon-mounted, ePTFE-coated, stainless-steel stent. To deploy a physician accesses the artery and blows up the balloon, forcing the device to expand. The balloon provides radial strength while the stent it deployed, but also

New material illuminates when exposed to chemicals on the body

MIT engineers and biologists teamed up and designed a living-cell-injected hydrogel that can illuminate when exposed to certain chemicals. The MIT team made wearable sensors using the hydrogel with living cells that lit up after touching a surface with certain chemicals. The new material has the potential to detect chemicals in the environment and the

Metallic hydrogen could be a reality: Why you should care

Harvard University scientists say they have created metallic hydrogen, a super material that until now has only been theoretical. If the claims pan out, they could open up a host of possibilities, including in the medical device field. That’s because metallic hydrogen theoretically should be superconductive at room temperature. MRIs, for example, would no longer

Exploring ePTFE sutures for surgical product development

Zeus Industrial Products has developed an expanded polytetrafluoroethylene (ePTFE) suture based on physicians’ needs. In this podcast, Bruce Anneaux, corporate director of research and development at Zeus, reviews the material properties of Aeos ePTFE and the company’s latest offering, a suture monofilament. The structure of the Aeos material consists of solid nodes interconnected by a matrix of

Boston Sci giving lift to new erectile dysfunction device

Want to put some lead in your pencil? Try nitinol instead. The wonder metal—a nickel-titanium alloy with heat-activated shape memory—has proved essential for Wisconsin and Illinois researchers building what British tabloids are calling a “bionic penis.” Chuckles aside, the proposed implant has enough potential advantages over existing erectile dysfunction treatment implants that Boston Scientific officials

MasterSil 910Med: One part, medical grade silicone system cures rapidly

MasterSil 910Med is a one part silicone for bonding, sealing and coating primarily for medical devices. It passes both USP Class VI testing and ISO cytotoxicity specifications. As an acetoxy type system, it bonds exceptionally well to a wide variety of substrates including metals, composites, ceramics, glass as well as many rubbers and plastics. MasterSil

Minnesota Rubber & Plastics presents new high purity EPDM, FKM and NBR materials for the medical and pharma industries

Quadion, Minnesota Rubber and Plastics (MRP) introduces a new portfolio of materials formulated for Medical and Pharma applications. Using only the most high purity ingredients, these comply with existing and proposed regulations around elastomeric products.

Global medical polymers market expected to hit $19 billion by 2022

The polymers market, which includes PVC, polypropylene, polyethylene, polystyrene, polycarbonate, PEEK, hydrogel, styrenic block copolymer, rubber latex, biodegradable, PLA used in medical applications should reach over $19 billion by 2022, with an estimated CAGR of 13.0%, according to Allied Market Research. Key findings The bioresorbable plastics (PGA) of polymer market is expected to grow at

Scientists tissue engineer human intestines and functioning nerves

Scientists report in Nature Medicine using human pluripotent stem cells to grow human intestinal tissues that have functioning nerves in a laboratory, and then using these to recreate and study a severe intestinal nerve disorder called Hirschsprung’s disease. Published online Nov. 21, the findings describe an unprecedented approach to engineer and study tissues in the

One component elastomeric system features excellent thermal conductivity

Master Bond X5TC is an elastomeric system that has a thermal conductivity of 10 to 12 BTU in/ft•2 hr•°F (1.44 to 1.73 W/m•K) while maintaining solid electrical insulation properties. This one part, no mix adhesive/sealant has a paste-like consistency and is easy to use. It readily cures in 8 to 12 hours at room temperature

Biomedical ‘skin-like bandage’ is stretchy, durable and long lasting

A skin-like biomedical technology that uses a mesh of conducting nanowires and a thin layer of elastic polymer might bring new electronic bandages that monitor biosignals for medical applications and provide therapeutic stimulation through the skin. The biomedical device mimics the human skin’s elastic properties and sensory capabilities, and it was developed at Purdue University. “It

Artificial muscles show more flex

Artificial muscles made significant gains when a literal twist in the development approach uncovered the tensile—or stretchy—abilities of polymer fibers once they were twisted and coiled into a spring-like geometry. In a similar manner to the powerful climbing tendrils of cucumber plants, the unique geometry gives the coil a flexing motion when fiber material shrinks—a
